1. List of possible issues

   1) after talking with Dave Meekins, he brought up the fact that the cryo-target will have to be reconfigured. Pi0 experiment will have only 6cm cryo-target
   
   
   2) coolant requirement on 20cm cell
   
   
   3) deuterium and ⁴He might not be able to run at the same time (3 cryo changes: ³He --> D --> ⁴He) (from discussion with Jian-Ping)
   
   
   4) getting ⁴⁸Ca (can we run everything but ⁴⁸Ca and come back for ⁴⁸Ca ?)
   
   
   5) left arm running only
